I am not too sure on how to integerating hibernate and hivemind (or if there
is a need to), maybe someone else can comment on this.
What I did is create my own InjectObjectWorker class with the fix, and packaged
it with my source code (it's a hack, I'm hoping future releases would solve
it). The classloader will pick up the one with the source code, not the one in
the jar file (in effect it shadows the original).
